Description

200902704 IX. Description of the invention: [Technical field to which the invention pertains] The present invention provides a lubricating oil composition, specifically, for use as engine oil, liquid house oil, thirteen turbine oil, compressor oil, gear oil, sliding friction oil, bearing Lubricating oil composition of oil and bismuth oil. [Prior Art] In the machine equipment, silver resistance is required as the basic characteristic of the lubricating oil to maintain the temperature of the lubricating oil in the tower tank of the machine and the apparatus according to the use of the second and lower %, which may make such The lubricating oil in the tower tank is mixed with water # or mixed with water due to the cooling water pipe (4). If it is necessary to suppress the deterioration of the sludge in the lubricating oil used in the machine equipment and produce a large amount of sludge, for example, oil may occur: the base may be insufficiently supplied and the lubricating oil may not be sufficiently supplied to increase the risk of failure. The generated sludge accumulates in the bearing parts and cannot form a proper oil film due to the bearing parts and paint, resulting in bearing damage. In addition, the tube:::"" sludge may block hydraulic fluid compositions known to be pumped by servo mechanisms. ..., has a low ~ Ni produced lubrication • = Bu 'good friction characteristics in recent years has been nm composition: there are effective to reduce friction losses in machines and devices and through the * _ wood coefficient (μ) to reach a large number of energy Economic needs. Moreover, the hydraulic device is widely used in the construction of machinery and other equipment = the dynamic of the machine, the code, the right, the high friction coefficient of the hydraulic oil-sliding friction rod, in the hydraulic red reciprocating ... A momentary slippage occurs, and the cylinder may have 200902704 vibrating, vibrating, screaming and its A ten-sounding voice, so it becomes impossible to control ', A ^ 0, t profit / with satisfactory accuracy.仗堙° is also available. See Japanese Laid-Open Patent Publication No. 9-1 1 1277 (1997). Because , , , τ reduces the friction coefficient of the π oil to make the hydraulic cylinder smooth and accurate movement necessary. SUMMARY OF THE INVENTION The present invention is directed to obtaining a lubricating oil composition which has excellent corrosion resistance and produces only S sludge. However, the anti-surname agent added to improve the durability may be a substance that produces sludge due to thermal deterioration. Therefore, an important issue is to maintain a balance between the control and the sludge. Another important issue is the friction coefficient of the lower plate, μ, 丄a cattle low-run π oil and the high industrial lubricant of Langyue. If there will be a shortage, five, and mountains. ^ Take the lubricant composition for solving 11 problems; in the hydraulic oil of the hydraulic device, there will be no chattering, propagating, screaming and other improper squatting in the hydraulic tank. Phenomenon, and will be able to control the liquidity of the maneuver. SUMMARY OF THE INVENTION The present invention is directed to obtaining a lubricating oil composition which suppresses the generation of grinding, s + and chi/ni, and has sufficient energy-saving characteristics to have good operational efficiency. In this regard, Ben·Ming Technology-Γ_ Μ people in January refined aspartic acid derivatives and epoxidized esterification & as an additive into the base oil, hk〆_ 丞 oil t 'preferred sulfur content A lubricating oil composition that does not exceed 300 ppm of a fine base oil or a person, or a slag, provides an industrial lubricant: Further, in the preferred embodiment, I month is provided by adding an aliphatic amine as an additive to a lubricating oil composition which has extremely low sludge generation and excellent viscous behavior. According to the present invention, the composition of the lubricating oil which inhibits abrasion and sludge generation is further improved. In addition, the external foreign government kh can effectively reduce the friction loss of the 200902704 caused by various types of industrial devices and ensure the province, s ^ 〇 Ganyishan owed the name to this source. Moreover, if it is used as a hydraulic oil, its hunting is controlled by the accuracy of reducing the friction coefficient, and the hydraulic pressure is not controlled in the liquid... Yan movement, shock:: normal noise and other phenomena. "And /, he does not use the base oil of this muddy oil composition, mineral oil and synthetic oil known as high base oil can be used.
